  • D&rsquo;Arcy&rsquo;s Book Club - The New Strategic Selling

    - by D'Arcy Lussier
    The New Strategic Selling Miller and Heiman Amazon.ca Amazon.com Chapters Everybody is a salesmen. Every day, without knowing it, we sell something to someone. Now, the typical vision people think of when they hear the word “sales” is the sleazy used car salesperson who does whatever they can to get you to buy the clunker on their lot. But selling is not an action tied to money and products. Selling is about convincing people to see your point of view and act on it. If you want your company to cover a trip to a conference, you may have to sell the idea to your boss. If you want to buy that new big screen TV, you have to sell the idea to your significant other. If you want to go on a weekend fishing trip with the boys you might be called in to help sell the idea to your buddies wife. We all sell, but we don’t all sell very well. So enter The New Strategic Selling, a book based on the sales course put on by the Miller-Heiman group. In fact, this isn’t really a “New” strategy to selling as its been around for a number of years. But the concepts they present, the ideas about selling, these are still very radical based on what most of us have experienced. Gone are the high pressure, win at all cost, GlenGarry-GlenRoss style of sales…instead the book presents a framework to switch to need-based selling. It’s the idea that instead of going in raving about a product or service, you build a relationship where the buyer expresses what their needs are and your response is to present a solution that best fits that need. Instead of focussing on the amount of money you can squeeze out of a client, you focus on whether everyone wins, that they receive win-results from the engagement, that repeat business is developed over time delivering value over and over again. The great thing about the book is that what it teaches…things like how to identify different buying influencers, how to prepare for meetings, techniques to solicit information about what the buyer is really thinking/feeling…these things are entirely applicable in *any* situation that you need to sell to someone…and remember: selling is convincing people to see your point of view and act on it. So that new big screen TV you want to buy but need to convince your wife on? This book can help you. That training opportunity you want your company to send you on? This book can help you. The upgrade to your community park that you want to lobby the local civic authorities for? This book can help you. The book is a bit wordy. I found that the length could have been reduced and the points still have gotten across. That’s really the only knock that I have though; the insight that it provides is so worthwhile that having to chew through extra words is well worth it. You definitely don’t have to be a professional salesperson to benefit from this book. Rating: 4/5

  • Paragraph formatting in a WPF RichTextBox?

    - by David Veeneman
    I need to apply paragraph formatting to a selection in a rich text box. My RTB will behave the same way as the rich text boxes on StackOverflow--the user can type text into the RTB, but they can also enter code blocks. The RTB will apply very simple formatting to the code block--it will change the font and apply a background color to the entire block, similar to what you see in the code block below. Changing the font is pretty straightforward: var textRange = new TextRange(rtb.Selection.Start, rtb.Selection.End); textRange.ApplyPropertyValue(TextElement.FontFamilyProperty, "Consolas"); textRange.ApplyPropertyValue(TextElement.FontSizeProperty, 10D ); Now I need to apply some paragraph-level formatting. I need to set the paragraph margin to 0, so I don't get a blank line between code lines, and I need to set the paragraph background color. Here's my problem: I can't figure out how to get the paragraph elements from the selection, so that I can apply formatting. Any suggestions? An example of how to apply the Margin and Background properties would be incredibly helpful. Thanks!

  • Exporting makefile from Eclipse CDT

    - by Alex Farber
    I have C++ project in the Ubuntu OS, Eclipse CDT. My final goal is to build the project binaries for FreeBSD OS. The first test. I create simple C++ CDT project with main.cpp file: cout << "OK" << endl; and build it. Then I open Terminal window in Release directory: alex@alex-linux:~/workspace/HelloWorld/Release$ ls HelloWorld main.d main.o makefile objects.mk sources.mk subdir.mk alex@alex-linux:~/workspace/HelloWorld/Release$ rm HelloWorld main.d main.o alex@alex-linux:~/workspace/HelloWorld/Release$ ls makefile objects.mk sources.mk subdir.mk alex@alex-linux:~/workspace/HelloWorld/Release$ make Building file: ../main.cpp Invoking: GCC C++ Compiler g++ -O3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o"main.o" "../main.cpp" Finished building: ../main.cpp Building target: HelloWorld Invoking: GCC C++ Linker g++ -o"HelloWorld" ./main.o Finished building target: HelloWorld alex@alex-linux:~/workspace/HelloWorld/Release$ ./HelloWorld OK alex@alex-linux:~/workspace/HelloWorld/Release$ So far, so good. Now I copy the whole project tree to FreeBSD and trying to build it: $ cd /home/alex/project $ ls main.cpp release $ cd release $ ls makefile objects.mk sources.mk subdir.mk $ make "makefile", line 5: Need an operator "makefile", line 10: Need an operator "makefile", line 11: Need an operator "makefile", line 12: Need an operator CDT-generated makefile doesn't work. This is makefile beginning: $ Automatically-generated file. Do not edit! -include ../makefile.init RM := rm -rf $ All of the sources participating in the build are defined here -include sources.mk -include subdir.mk -include objects.mk ... Line 5 is -include ../makefile.init. Really, there is no such file. But it works by some way on Ubuntu computer. What is the trick, how can I build this? BTW, manually written makefile works: all: g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o"main.o" "../main.cpp" g++ -o"HelloWorld" ./main.o Note: $ in makefile is actually #, I replaced it because # creates formatting problems inside of stackoverflow pre block.

  • ConcurrentDictionary and updating values

    - by rboarman
    Hello, After searching via Google and coming up empty, I decided to ask the gurus here on StackOverflow. I am trying to update entries in a ConcurrentDictionary something like this: class Class1 { public int Counter { get; set; } } class Test { private ConcurrentDictionary<int, Class1> dict = new ConcurrentDictionary<int, Class1>(); public void TestIt() { foreach (var foo in dict) { foo.Value.Counter = foo.Value.Counter + 1; // Simplified example } } } Essentially I need to iterate over the dictionary and update a field on each Value. I understand from the documentation that I need to avoid using the Value property. Instead I think I need to use TryUpdate except that I don’t want to replace my whole object. Instead, I want to update a field on the object. After reading this: http://blogs.msdn.com/b/pfxteam/archive/2010/01/08/9945809.aspx Perhaps I need to use AddOrUpdate and simply do nothing in the add delegate. Does anyone have any insight as to how to do this? Thank you, Rick

  • UIImagePicker on full screen on iPad

    - by Archip
    For my tests, I need to create a simple app on the iPad to step 1. loads an image from the Photo library (UIImagePickerController). step 2. Then, this image is converted into texture and displayed into an OpenGL ES view. I started to define the app with the XCode Open GL ES template. Step 2 is Okay. But I have a problem launching the UIImagePickerController (step 1). On iPad, to create a UIImagePickerController, we need to use a UIPopoverController. But to create a UIPopover, we need to attach it to a content view controller In my app, I dont want to define a specific view controller (Navigation or SplitView or TabBar...). I just need to have the UIImagePicker displayed on full screen when launching the app. I am looking for a programatical solution with a minimum of lines of code added from the Open GL ES iPad template, to perform step 1 (step 2 is okay for me). any code available? Thank you for your help Seb

  • Use RegEx in Java to extract parameters in between parentheses

    - by lars_bx
    I'm writing a utility to extract the names of header files from JSPs. I have no problem reading the JSPs line by line and finding the lines I need. I am having a problem extracting the specific text needed using regex. After looking at many similar questions I'm hitting a brick wall. An example of the String I'll be matching from within is: <jsp:include page="<%=Pages.getString(\"MY_HEADER\")%>" flush="true"></jsp:include> All I need is MY_HEADER for this example. Any time I have this tag: <%=Pages.getString I need what comes between this: <%=Pages.getString(\" and this: )%> Here is what I have currently (which is not working, I might add) : String currentLine; while ((currentLine = fileReader.readLine()) != null) { Pattern pattern = Pattern.compile("<%=Pages\\.getString\\(\\\\\"([^\\\\]*)"); Matcher matcher = pattern.matcher(currentLine); while(matcher.find()) { System.out.println(matcher.group(1).toString()); }} I need to be able to use the Java RegEx API and regex to extract those header names. Any help on this issue is greatly appreciated. Thanks! EDIT: Resolved this issue, thankfully. The tricky part was, after being given the right regex, it had to be taken into account that the String I was feeding to the regex was always going to have two " / " characters ( (/"MY_HEADER"/) ) that needed to be escaped in the pattern. Here is what worked (thanks to the help ;-)): Pattern pattern = Pattern.compile("<%=Pages\\.getString\\(\\\\\"([^\\\\\"]*)");

  • Intellij Javafx artifact - how do you make it?

    - by Louis Sayers
    I've been trying all day to turn my javafx application into a jar file. I'm using Java 1.7 update 7. Oracle has some information, but it just seems scattered all over the place. Intellij is almost doing the job, but I get the following error: java.lang.NoClassDefFoundError: javafx/application/Application Which seems to say that I need to tell java where the jfxrt.jar is... If I add this jar to my classpath info for the manifest build in intellij - ctrl+shift+alt+s - Artifacts - Output Layout tab - Class Path, then I get another error: Could not find or load main class com.downloadpinterest.code.Main It seems strange to have to include jfxrt.jar in my class path though... I've tried to create an ant script as well, but I feel like IntelliJ is 90% of the way there - and I just need a bit of help to figure out why I need to include jfxrt.jar, and why my Main class isn't being found (I'm guessing I need to add it to the classpath somehow?). Could anyone clue me up as to what is happening? I had a basic gui before which worked fine, but JavaFX seems to be making life complicated!

  • Reverse engineering and patching a DirectX game?

    - by yodaj007
    Background I am playing Imperishable Night, one of the Touhou series of games. The shoot button is 'z', moving slower is 'shift', and the arrow keys move. Unfortunately for me, using shift-z ghosts my right arrow key, so I can't move to the right while shooting. This ghosting happens in all applications, and switching keyboards fixes it. Goal I want to locate in the disassembled code the directx function that gets the keyboard input and compares it against the 'z' key, and change that key to 'a'. I'm considering this a fun project. Assuming the size of the scan codes are the same, this should be fairly simple. And because the executable is only 400k, maybe this will provide a unique opportunity for me to explore the dark side of the computing underworld (kidding). Relevant experience I have some experience with coding in assembly, but not in the disassembly of such. I have no experience with the DirectX apis. Question I need some guidance. I've found a listing of directx keyboard scan codes, and a program called PEExplorer that looks like it will do what I need. Is there a means by which I can turn some of the assembly with C function calls so it's more easily read? I will need to locate where the game retrieves the currently pressed keys, compares those against a list, and it's that list I need to modify. Any input would be greatly appreciated.

  • How do you host multiple public facing websites on a VPS?

    - by Petras
    We host about 30 websites using typical shared hosting plans using ASP.NET and SQL 2000/2005/2008. I am now wondering about hosting all of these websites using our own virtual private server such as http://www.crystaltech.com/vps.aspx This is clearly cheaper but comes with a lot of questions I need answers to: Is the risk of having to keep this VPS server up and running worth it? Until now, the host provider has managed the server and we have not had to worry about crashes, downtime, software patches etc. We are not server administrators, we are programmers, so this is not really our expertise. On the other hand, it may not be hard to learn. When we make a website live, we log in to a domain management control panel and change the primary and secondary name servers to point to our shared web host: Eg ns1.sharedwebhost.com and ns2.sharedwebhost.com These name servers are going to have to change when we have a VPS. I don’t understand anything about how to set this up. Is there some useful info anyone could direct me to? Or is there software we need to install to make the primary and secondary name servers work on our VPS? The control panel we have for shared hosting comes with DNS management like this: What software would I need to install to create this for each site we host at a VPS? The control panel we have for shared hosting also comes with a POP email interface that allows email addresses to be added easily: Is this something that can be easily set up at a VPS so clients can manage their own email addresses? Is there software we need to install to make this work?

  • Multilingual spellcheck on WPF richtextbox

    - by sub-jp
    I need to turn spellcheck on for a richtextbox, and set the language to one the user has picked from a drop down. For now, I'm just testing it by building the richtextbox in xaml and providing a language to the xaml language attribute. I've read two different resources and one says I need to set the language attribute, and the other says I need to set the xml:lang attribute. Neither seems to work. I've tried setting either one to "es" for Spanish, and I've also tried setting both to "es". I've also tried french by setting them to "fr-FR", without success. The only thing that happens is that english words aren't marked, but the other language words are marked as misspelled. I also read that I need to change the keyboard language. This would be a problem for my application as the language within the application needs to be switched on the fly, so having the end user go to their keyboard settings just so spellcheck will work is a problem. However, I've changed my keyboard settings, and spell check still does not work properly. This time it doesn't mark anything as misspelled, even misspelled english words. What am I missing? Edit: some links to my references above http://msdn.microsoft.com/en-us/library/system.windows.controls.spellcheck(v=VS.100).aspx http://www.dev102.com/2008/03/25/customize-spellcheck-on-wpf-text-controls/ http://books.google.com/books?id=clLc5BBHqRMC&pg=PA121&lpg=PA121&dq=C%23+wpf+enable+spellcheck&source=bl&ots=_r59pZRDjP&sig=yHMBc39EHKK5gaRMzxlBaEsY890&hl=en&ei=oXnIS8zWH4G88gaq48yGBw&sa=X&oi=book_result&ct=result&resnum=6&ved=0CBMQ6AEwBQ#v=onepage&q&f=false

  • Getting the current EnvDTE or IServiceProvider when NOT coding an Addin

    - by Vaccano
    I am coding up some design time code. I want to use this snippet: (Found here) var dte = (EnvDTE.DTE) GetService(typeof(EnvDTE.DTE)); if (dte != null) { var solution = dte.Solution; if (solution != null) { string baseDir = Path.GetDirectoryName(solution.FullName); } } Problem is that this does not compile. (GetService is not a known method call) I tried adding Microsoft.VisualStudio.Shell (and Microsoft.VisualStudio.Shell.10.0) but it did not help. In looking around on the internet I found that you need a IServiceProvider to call this. But all the examples that show how to get an IServiceProvider use a EnvDTE. So, to get the current EnvDTE I need IServiceProvider. But to get an IServiceProvider I need an EnvDTE. (There is a hole in my bucket...) So, here is my question: In a normal WPF Application, how can I get the current instance of EnvDTE? NOTE: I am not looking for any old instance of EnvDTE. I need the one for my current Visual Studio instance (I run 3-4 instances of Visual Studio at a time.)

  • Populating array of input fields as alternate fields using jQuery UI datepicker

    - by Micor
    I am using jquery ui datepicker in order to populate start and end dates for multiple events on the same page, the number of events is dynamic and I need to post day, month and year as separate fields, so I have something like this: <input type="text" name="event[0].startDate" class="date"/> <input type="hidden" name="event[0].startDate_day" class="startDate_day" /> <input type="hidden" name="event[0].startDate_month" class="startDate_month" /> <input type="hidden" name="event[0].startDate_year" class="startDate_year" /> <input type="text" name="event[0].endDate" class="date"/> <input type="hidden" name="event[0].endDate_day" class="endDate_day" /> <input type="hidden" name="event[0].endDate_month" class="endDate_month" /> <input type="hidden" name="event[0].endDate_year" class="startDate_year" /> event[1]... event[2]... I started working on jQuery functionality and this is what I have so far, which will populate alternate fields for startDate by class, of course it will not do what I need because I need to populate by field name rather then class: $(".date").datepicker({ onClose: function(dateText,picker) { $('.startDate_month').val( dateText.split(/\//)[0] ); $('.startDate_day').val( dateText.split(/\//)[1] ); $('.startDate_year').val( dateText.split(/\//)[2] ); }}); I need help figuring out how can I get the name of the input field within datepicker function so the alternate field assignment done by that field name + _day, month, year so this function can work for all the events on the page, making function above look more like: $(".date").datepicker({ onClose: function(dateText,picker) { $('input[' + $name + '_month' + ']').val( dateText.split(/\//)[0] ); $('input[' + $name + '_day' + ']').val( dateText.split(/\//)[1] ); $('input[' + $name + '_year' + ']').val( dateText.split(/\//)[2] ); }}); Hope that makes sense :) Thanks

  • How can I attach a Silverlight OOB to a Winforms panel?

    - by JohnMcCon
    Summary: I want the prettiness of Silverlight/WPF in part of my current Winforms application. The application can only have access to the full .NET Framework 2.0, no more and no less. The only possibility I can think of is a Silverlight OOB application that utilizes Com+ Automation but I can't figure out how to attach the Silverlight application to a panel within the parent Winforms application. Details: I currently have a winforms application, and want to take advantage of the improved GUI features in WPF but to many of my users are still running .Net Framework 2.0 and refuse to update to 3+. So WPF is not an option for me. I know Silverlight is just a subset of WPF, but it has most of the features I'm looking for and only requires the Silverlight plug-in. I've read about Silverlight 4's Com+ Automation, which would give me access to the full desktop .Net Framework 2.0 (which I need). In order for Com+ Automation to work in Silverlight I need elevated trust and the only way I can find to gain elevated trust is to make my Silverlight application Out-Of-Browser (OOB). My problem is that the OOB application seems to run in its own container window and I need the Silverlight application embedded inside a panel in my Winforms application. My Winforms application does not need to communicate with the Silverlight application and vice-versa, this is purely to have everything contained and displayed in one window. If there is another way to get my desired result that I have not thought of feel free to suggest it.

  • Boost.Program_options fixed number of tokens

    - by kloffy
    Boost.Program_options provides a facility to pass multiple tokens via command line arguments as follows: std::vector<int> nums; po::options_description desc("Allowed options"); desc.add_options() ("help", "Produce help message.") ("nums", po::value< std::vector<int> >(&nums)->multitoken(), "Numbers.") ; po::variables_map vm; po::store(po::parse_command_line(argc, argv, desc), vm); po::notify(vm); However, what is the preferred way of accepting only a fixed number of arguments? The only solution I could come is to manually assign values: int nums[2]; po::options_description desc("Allowed options"); desc.add_options() ("help", "Produce help message.") ("nums", "Numbers.") ; po::variables_map vm; po::store(po::parse_command_line(argc, argv, desc), vm); if (vm.count("nums")) { // Assign nums } This feels a bit clumsy. Is there a better solution?

  • Two DIV layers: resize top DIV based on dynamic height of bottom DIV

    - by user1650713
    I have two DIV layers, one above the other. In the top DIV, there is an image, and in the bottom DIV, there is a block of text. The amount of text in the bottom DIV will change, thus increasing and decreasing the required height. I need to dynamically decrease the height of the image in the top DIV based on how much height is required for the bottom. I have exactly 600px vertical space available. For example: If the bottom DIV requires 200px height, I need for the image to change height to 400px. If the bottom DIV requires 300px height, I need for the image to change height to 300px. I know that I can make the image height 100% of the top DIV, thus allowing it to expand or contract as needed. The issue is that I need for the bottom DIV to be able to expand freely and for the top DIV to react accordingly. In other words, I cannot have either be a fixed height. <div id="topdiv"> <img src="example.png" alt="This image needs a height based on the bottom div" /> </div> <div id="bottomdiv"> This text needs to be able to expand or contract freely </div> Can anyone help?

  • Double split in C

    - by Dmitri
    Hi again dear community! OK. For example I have this line in my txt file: 1|1,12;7,19;6,4;8,19;2,2 . As you can see, it has 2 parts, separated by "|". I have no problems getting both parts, and separating second part ( 1,12;7,19;6,4;8,19;2,2 ) using ";" separator. BUT I do have problems with separating further by "," to get first and second number of each set. This is my current code: result = strtok(result, ";"); while(result != NULL ) { printf("%s\n", result); result = strtok(NULL, ";"); } It outputs me: 1,12 7,19 6,4 8,19 2,2 OK, great. But when I try to 'strtok' (I'm using this method for splitting) like this: result = strtok(result, ";"); while(result != NULL ) { //printf("%s\n", result); help = strtok(result, ","); while(help != NULL) { printf("<%s>", help); help = strtok(NULL, ","); } result = strtok(NULL, ";"); } I only get "<1,<12" like there is only one set in this set of numbers. I dont understand where are the rest of the numbers. Instead, output should be: <1,<12,<7,<19,<6,<4,<8,<19,<2,<2. Could someone please give a solution, how to get EACH number of each set this set of numbers. Maybe there are other methods or I'm doing something wrong :) Thank you! Best Regards, Dmitri

  • Getting started with character and text processing (encoding, regular expressions)

    - by TK
    I'd like to learn foundations of encodings, characters and text. Understanding these is important for dealing with a large set of text whether that are log files or text source for building algorithms for collective intelligence. My current knowledge is pretty basic: something like "As long as I use UTF-8, I'm okay." I don't say I need to learn about advanced topics right away. But I need to know: Bit and bytes level knowledge of encodings. Characters and alphabets not used in English. Multi-byte encodings. (I understand some Chinese and Japanese. And parsing them is important.) Regular expressions. Algorithm for text processing. Parsing natural languages. I also need an understanding of mathematics and corpus linguistics. The current and future web (semantic, intelligent, real-time web) needs processing, parsing and analyzing large text. I'm looking for some resources (maybe books?) that get me started with some of the bullets. (I find many helpful discussion on regular expressions here on Stack Overflow. So, you don't need to suggest resources on that topic.)

  • Is there an "embedded DBMS" to support multiple writer applications (processes) on the same db files

    - by Amir Moghimi
    I need to know if there is any embedded DBMS (preferably in Java and not necessarily relational) which supports multiple writer applications (processes) on the same set of db files. BerkeleyDB supports multiple readers but just one writer. I need multiple writers and multiple readers. UPDATE: It is not a multiple connection issue. I mean I do not need multiple connections to a running DBMS application (process) to write data. I need multiple DBMS applications (processes) to commit on the same storage files. HSQLDB, H2, JavaDB (Derby) and MongoDB do not support this feature. I think that there may be some File System limitations that prohibit this. If so, is there a File System that allows multiple writers on a single file? Use Case: The use case is a high-throughput clustered system that intends to store its high-volume business log entries into a SAN storage. Storing business logs in separate files for each server does not fit because query and indexing capabilities are needed on the whole biz logs. Because "a SAN typically is its own network of storage devices that are generally not accessible through the regular network by regular devices", I want to use SAN network bandwidth for logging while cluster LAN bandwidth is being used for other server to server and client to server communications.

  • Delete array of size 1

    - by Arne
    This is possibly a candidate for a one-line answer. I would like know it anyway.. I am writing a simple circular buffer and for some reasons that are not important for the question I need to implement it using an array of doubles. In fact I have not investiated other ways to do it, but since an array is required anyway I have not spent much time on looking for alternatives. template<typename T> class CircularBuffer { public: CircularBuffer(unsigned int size); ~CircularBuffer(); void Resize(unsigned int new_size); ... private: T* buffer; unsigned int buffer_size; }; Since I need to have the buffer dynamically sized the buffer_size is neither const nor a template parameter. Now the question: During construction and in function Resize(int) I only require the size to be at least one, although a buffer of size one is effectively no longer a buffer. Of course using a simple double instead would be more appropriate but anyway. Now when deleting the internal buffer in the destructor - or in function resize for that matter - I need to delete the allocated memory. Question is, how? First candidate is of course delete[] buffer; but then again, if I have allocated a buffer of size one, that is if the pointer was aquired with buffer = new T[0], is it still appropriate to call delete[] on the pointer or do I need to call delete buffer; (without brackets) ? Thanks, Arne

  • How to test IO code in JUnit?

    - by add
    I'm want to test two services: service which builds file name service which writes some data into file provided by 1st service In first i'm building some complex file structure (just for example {user}/{date}/{time}/{generatedId}.bin) In second i'm writing data to the file passed by first service (1st service calls 2nd service) How can I test both services using mocks without making any real IO interractions? Just for example: 1st service: public class DefaultLogService implements LogService { public void log(SomeComplexData data) { serializer.write(new FileOutputStream(buildComplexFileStructure()), data); or serializer.write(buildComplexFileStructure(), data); or serializer.write(new GenericInputEntity(buildComplexFileStructure()), data); } private ComplextDataSerializer serializer; // mocked in tests } 2nd service: public class DefaultComplexDataSerializer implements ComplexDataSerializer { void write(InputStream stream, SomeComplexData data) {...} or void write(File file, SomeCompexData data) {...} or void write(GenericInputEntity entity, SomeComplexData data) {...} } In first case i need to pass FileOutputStream which will create a file (i.e. i can't test 1st service) In second case i need to pass File. What can i do in 2nd service test if I need to test data which will be written to specified file? (i can't test 2nd service) In third case i think i need some generic IO object which will wrap File. Maybe there is some ready-to-use solution for this purpose?

  • How to implement a counter when using golang's goroutine?

    - by MrROY
    I'm trying to make a queue struct that have push and pop functions. I need to use 10 threads push and another 10 threads pop data, just like i did in the code below. Questions : 1. I need to print out how much i have pushed/popped, but i don't know how to do that. 2. Is there anyway to speed up my code ? the code is too slow for me. package main import ( "runtime" "time" ) const ( DATA_SIZE_PER_THREAD = 10000000 ) type Queue struct { records string } func (self Queue) push(record chan interface{}) { // need push counter record <- time.Now() } func (self Queue) pop(record chan interface{}) { // need pop counter <- record } func main() { runtime.GOMAXPROCS(runtime.NumCPU()) //record chan record := make(chan interface{},1000000) //finish flag chan finish := make(chan bool) queue := new(Queue) for i:=0; i<10; i++ { go func() { for j:=0; j<DATA_SIZE_PER_THREAD; j++ { queue.push(record) } finish<-true }() } for i:=0; i<10; i++ { go func() { for j:=0; j<DATA_SIZE_PER_THREAD; j++ { queue.pop(record) } finish<-true }() } for i:=0; i<20; i++ { <-finish } }

  • Which combing css technique?

    - by DotnetShadow
    Hi there, Which of the following would you say is the best way to go when combining files for CSS: Say I have a master.css file that is used across all pages on my website (page1.aspx, page2.aspx) Page1.aspx - A specific page that has some unique css that is only ever used on that page, so I create a page1.css and it also uses another css grids.css Page2.aspx - Another specific page that is different from all other pages on the site and is different to page1.aspx, I'll name this page2.aspx and make a page2.css this doesn't use grids.css So would you combine the scripts as: Option1: Combine scripts csshandler.axd?d=master.css,page1.css,grids.css when visiting page1 Combine scripts csshandler.axd?d=master.css,page2.css when visiting page2 Benefits: Page specific, rendering quicker since only selectors for that page need to be matched up no unused selectors Drawback: Multiple combinations of master.css + page specific hence master.css has to be downloaded for each page Option2: Combine all scripts whether a page needs them or not csshandler.axd?d=master.css,page1.css,page2.css,grids.css (master, page1 and page2) that way it gets cached as one. The problem is that rendering maybe slower since it will have to try and match EVERY selector in the css with selectors on the page even the missing ones, so in the case of page2.aspx that doesn't use grids.css the selectors in grids.css will need to be parsed to see if they are in page2 which means rendering will be slow Benefits: One file will ever be downloaded and cached doesn't matter what page you visit Drawback: Unused selectors will need to be parsed by the browser slower rendering Option3: Leave the master file on it's own and only combine other scripts (the benefit of this is because master is used across all pages there is a chance that this is cached so doesn't need to keep on downloading csshandler.axd?d=Master.css csshandler.axd?d=page1.css,grids.css Benefits: master.css file can be cached doesn't matter what page you visit. Not many unused selectors as page spefic is applied Drawback: Initially minimum of 2 HTTP request will have to be made What do you guys think? Cheers DotnetShadow
